Round the buoys, or offshore

A short windward-leeward and a night at sea ask different things of a boat. Here is how this one does in each.

Speed in knots at 20 knots of true wind. Green marks the angles that pay: the closest useful beat and the deepest run worth sailing.

Where it wins and where it pays

Every boat is judged against its own measurements — length, weight, sail area. The quicker those say it should be, the more it has to deliver just to break even. Going fast is not enough: it has to go faster than its own numbers promised.

It needs pressure to show what it can do. On a windy coastal course it is in its element; on a light-air windward-leeward it has to be sailed well to hold on.

Where it gains

Its best ground is on the beam once it pipes up, where it goes better than its measurements say it should, and by a margin worth having.

Where it pays

It falls short to windward in the light stuff, giving away time it never gets back.

Above the line it delivers more than promised and gains on the fleet. Below, it falls short. Move the wind: plenty of boats sit on one side in the light and the other when it blows.

Full width is 0.8 kn either way.

At 10 knots this design makes back more than its rating asks on the beam reach.

Nearly all carry a folding propeller. A bowsprit is standard across the fleet. Crew weight is declared around 840 kg.

Rigging

Dufour 455 rig and sail dimensions

A Dufour 455 carries 14.23 m of mainsail hoist on a 4.86 m boom, a forestay 15.28 m above the deck and a 6.10 m bowsprit. Typical figures across the 2 boats measured under the current VPP, with the range each one spans.
